Got one of these recently for a build I was doing for a friend. It's a VERY impressive budget monitor, No physical adjustment of any sort and no bundled DVI cable but more than made up for on the image quality, which was better than most of the more expensive alternatives in its class.

Seen these appearing for under £100 recently so you might get a fraction cheaper if you keep looking, but wouldn't have thought it would go much below this mark tbh, so if you're after a genuine qualty 22" look no further.
